To all whom it may concern Be 1t known that I, GIUSEPPE AnToMo PIETRO PROVAY, a subject of the King of Hungary, and resident of Lourenco Marquez, PortugueseEast Africa, have invented certain new and useful Improvements in Truck-Tipplers or Means for Discharging the Contents of-Trucks and like Vehicles,- of which the following is aspecification.

This invention appertains to a tippler,

dumper or similar contrivance for emptying other similar wheeled vehicles which traverse a permanent way or track.

It relates in particular to that type of device in which the truck is received bodily in a structure which is adapted to be revolved and thereby partially invert or incline the truck to discharge its contents.

The apparatus can be utilized for handling coal, ore or other fragmentary material,

- as well as grain or other granular material,

or pulverulent material, in bulk. For exbe used for transferring coal from railway trucks into a bin or bunker for the coaling of steamers, as well as for loading a ship or steamer with any material in bulk or for any other similar purpose.

The principal object of the present invention is to construct an efiicient apparatus, suitable for the purposes above specified, in a simple and comparatively inexpensive manner.

The apparatus is economical to operate as the tipping of the trucks is effected with the expenditure of a minimum of power and the power requisite for lifting'the truck is alample, it can ways proportional to the weight of the truck trucks designed and its contents.

A valuable feature of the invention is that the apparatus can, if desired, be used for lifting the truck in order to discharge its contents into a chute, bin, bunker or the like above the level of the main track traversed by the trucks, thereby obviating the necessity for all inclines in the track and permitting the truck to be taken from the level of the track and the emptying of its contents to be effected at any desired height above the level of such track.

For emptying composite trucks or to be discharged either at the bottom or at the side, the lifting operation only is necessary.

Specification of Letters Patent.

Fig. 7 is a The chute is automatically raised into position beneath the truck and the contents of the latter can be discharged 'thereinto without tippingor inclining the truck.

The apparatus, with the exception of the control of the motor or its equivalent, is antomatic in operation, and consequently it is capable of being operated by a single attendant irrespective of the size or capacity of the trucks or of the quantity of material to be handled.

The tippler or dumping apparatus can be constructed to accommodate wagons or trucks of any type and size, z. 6., width, length, height and capacity, the arrangement being easily designed within any desired range of such dimensions; the length of track inside the tippler, the amount of movement transversely of the main track or permanent way allowed to a carriage which supports the length of track inside the tippier, and the extent of the movement of certain beams which engage and clamp the top of the truck, determining said range.

The invention will now be more fully described with the aid of the accompanying drawings, wherein- V Figure 1 represents the apparatus in end elevation. Fig. 2 is an elevation of the apparatus asseen from the back. Fig. 3 is a plan of certain parts of the apparatus. Fig. 4 is a part sectional front elevation of the tippler drawn to an enlarged scale with a truck, shown in dotted lines, in position therein.

tratin a further modified arrangement of the li ing and revolving ropes for the .tip-

ler. I p In the Construction of the tippler or dumper proper of the apparatus I employsee more particularly Figs. 4 and 5 a suitable number of cylindrical sections, according to the length of the longest truck which it is desired to tip. Each of these sections may, as shown in Fig. 4, be built up of a ring or hollow cylinder 1, rings 2,3 of L .section riveted or otherwise secured on the inside and at the ends ofthe ring or cylinder 1, and side or end plates 4, 5, the plates 4, 5 having apertures 6 in them exceeding the height and width of the largest truck.

The passage through the several cylindrical sections, provided by the openings 6 in the plates 4, 5, is lined with plates 7, as shown in Fig. 4, so as to inclose the space between the side plates 4, 5 on all sides. The several sections-the tippler in Fig. 4 is shown comprising-five of such sections-are securely connected together by means of longitudinal members or ties 8 of T, as shown, or any other suitable section or sections, preferably disposed in relation to each other as shown in Fig. 5, and angle brackets or suitably shaped pieces of plate 9 riveted orotherwise fixed to said members 8 and end plates 4, 5 to make the whole of said five sections a rigid, cylindrical, revoluble structure.

The revoluble structure or tippler, when 1 it is placed in a position to receive a truck ofi the main line or permanent way, (portions 10 of which are represented at each end of the tippler in Figs. 2 and 4) rests upon a bolster or cushion of wooden blocks or other suitable material 11-see Fig. 1, .which bolster is arranged upon a base or foundation 12 of concrete or other suitable material.

Upon the base or foundation 12 there is erected a super-structure comprising a suitable number of pairs of pillars or columns 13, arranged in two rows, one pair for each cylindrical section of the tippler. All the pillars or columns 13 of the super-structure are spanned and connected by arches 14- see F igs. 1 and 2the top of which arches is utilized as a platform for certain portions of the means for manipulating the tippler and its appurtenances.

The superstructure comprising the pillars or columns 13 and the arches 14 may be constructed of ferro-concrete, or of iron, or other suitable metal, timber or any other i suitable material or materials.

sov

In the inner and opposing surfaces of the pillars 13 and arches 14 are provided guideways 15which may conveniently consist of channel ironsin which run guide wheels 16 fixed to each of the several cylindrical sections of the tippler. Each section is shown provided with four of such guide-wheels at each side, revolubly secured thereto by means of brackets 17. The guide wheels 16 traverse the guides 15 when the tippler is lifted and rotated-as hereinafter explainedin order to tip a truck. The width between the guide-ways 15 in opposing pillars 13 is such that with the guide-wheels 16 positioned as shown-se'e Figs. 1 and 5the tippler .cannot be rotated until it has been raised to its maximum height, in which position it can rotate in-the curved guide-ways 18 in the upper portion of the superstruc- The guide wheels 16 or rollers 19, 20," or

both guide wheels 16 and rollers 19, 20 may, if desired, be supported by brackets, constructed integral. with, or connected to, pistons or their equivalent, arranged to work in cylinders or guides againstsuitable strong springs, in order to keep said guide wheels or rollers yieldingly in rolling contact with their guides.

The several sections of the revoluble structure o-r tippler carry what I may designate a cradle. This cradle consists of a suitable length of rail 22 for each section of the tippler. These rails as shown in Figs. 1 and 5 are downwardly inclined from the front to the back of the tippler and they are curved upwardly at both ends, the curvature thereof corresponding to the radius of the wheels 01 the carriage or traverser-hereinafter re-' ferred to-which travels upon them. The rails 22 are laidon the bottom plates 7, which are arranged at the desired inclination of said rails. 23, 24 indicate suitably shaped supports fixed to'the bottom lining plates 7 for supporting the curved ends of the rails 22. The bottom of the openings 6 in the plates 4, 5 of the several cylindrical sections are downwardly inclined from the front to the back to agree with the inclination of the rails 22 and bottom lining plates 7 and said openings are rounded or curved to correspond to the shape of the supports 23, 24. 1

The carriage. or traverser which travels on the several inclined rails 22 comprises for each rail twoside plates 25, 2 6 and a top plate 27. The side plates support the spindles 28 of the two peripherally grooved wheels or flanged rollers 29, 30 of the carriage. The side plates 25, 26 may, as shown at 31, be fashioned with bosses to form the bearings for the spindles 28. The several sections of the carriage or traverser may be main track or permanent way, an

- laterally of the rails 10 of the stationary traverser together with connected between the sections ofthe tippler by means of suitable stays,

Rollers or the like may, if desired, be provided and suitably fixed to the underside of the carriage and arranged to work or run in channel'iron or other suitable guidessecured to any or all of the cylindrical sections in order to keep the carriage on its rails 22 should the tippler be rotated while empty or without having a truck within it. 33, 34 represent the length of rails on which the truck. 35, the contents of which are to be dumped, runoff the rails 10 of the d 36, 37 represent check or L rails which are preferably provided on the inside of the rails 33, 34. The rails 33, 34 and check or L rails 36, 37 are suitably fixed upon the top plates 27 of the several sections of the carriage or traverser and serve for rigidly connecting the same. The carriage or traverser, as w' l he understood on reference to Figs. 1 and 5 of the drawings, can travel in a direction track or permanent way. As shown'in Fig. 4 the rails 33, 34 and check or L rails 36, 37 preferably extend a short distance beyond the two outermost sections of the tippler; 38 representing brackets for carrying the overhanging portions of said rails.

The several inclined rails 22 of the cradle are so designed and arranged within their respective sections of the tippler that when the carriage or traverser is at. rest at the lower end of said inclined rails-as shown in Figs. 1 and 5the rails 33, 34 which are mounted upon the carriage or traverser are alined with the rails 10 of the main track at both ends of the tippler. The cradle admits of the necessary travel, transversely of the main track rails 10, of the carriage .or'

the rails 33, 34 which are mounted upon it, for one side of the truck 35 to rest upon the inside of the tippler when the latter is rotated, as shown in dotted lines in Fig. 1, to empty the truck 35.

A mark or pointer 201see Fig. 8-may he provided and suitably fixed or made on, say, the first section of the tippler, and a mark be provided on the superstructure 13 as indicated at 202 in Fig. 8, the positions of the mark or pointer 201 and mark 202 being such that their coincidence would indicate to the driver or' operator that the tippler was then in the exact position for the lowering of the tippler to be commenced.

As shown in dotted lines in Fig. 8, a suitably shaped and inclined plate 200, com prising one or more pieces, may be provided and fixed to the tippler, the said plate being of the tippler and for of such a length as to extend between, or through and between, the several cylindrical sections of the tippler and to some extent beyond the two end sections, or so that it exceeds the length of thetippler in both directions, for the purpose of of the free fall of the truck to the movable chute 151, and for diverting the falling material (as indicated by the arrow) in a backward direction into the chute 151, and thereby minimize breakage of the material.

As shown in Figs. 1, 4 and 5 the several sections of the tippler are lined with timber .or other suitable material 39 on that side against which the truck 35 rests when the tippler is partially rotated. This timber lining-see more particularly Figs. 1, 5 and 6-is fixed to vertical beams or posts 3!) of timber or other suitable material which are secured to the inside lining plate 7. The boards or planks of said lining are also preferably connected together by means of intermediate vertical channel irons 39 Said timber lining 39, as shown in Fig. 4 extends the full distance between the several sectionssome distance beyond to afl'ord. a large surmaterial from the the end sections so as reducing the extent face for the side of the truck 35 to rest upon when it is inclined, in order to obviate the possi ilityof deforming ordamaging the truck by so inclining it. Those portions of the timber lining which extend beyond the end sections are supported by means of angle -brackets 39 suitably fixed to the outside of said outer sections and to said outer portions of the timber lining, and vertical stays or stiflening pieces 39 of U shape, suitably secured to their outer ends. If desired this timber lining 39 canbe placed upon springs instead of or in addition to the wooden beams 39 in order the better to buffer the truck 35 and so that the lining 39 will more readily adapt itself to the shape of the side of the truck. The travel of the truck 35 being short and its movement slow there is little acceleration. and consequently a minimum of shock or stress is put upon it when it comes into contact with the lining 39 as a result of the rotation of the tippler.

The inside lining plate 7 on the same side as and above the timber lining 39 is as shown in Fig. 6 of V shape in cross-section or made to diverge toward its point of attachment to the side plates to prevent a surface being formed upon which the material would lodge when the truck is emptied. The timber lining 39 is constructed to provide a vertical slot or groove 40 near each section of the tippler. Saidslots 40 are shown formed between the ends of the three upper planks tween the adjoining sections of the tippler. The aforesaid slots or grooves allow of the movement therein of certain clamping beams or bars 41, one of which is provided for each section of the tippler. These bars or beams 41 are adjustable vertically as will be hereinafter explained and serve, by engaging the top or upper edges of the sides of or boards which extend bei 43, one for each end of the bar. The one "weighted lever 42 is fulcrumed upon a spindle 44 fixed to one of the side plates of the section and it has attached to it a lever- 45 which it operates, The lever 45 has pivotally connected to its outer extremity a pair of links 46, 47. Links 46, 47 at their other and upper ends are pivotally connected by means of a pin 48 to a cross-head 49-see Fig. 6 and to the end of the bar or beam 41. The cross-head 49 works in vertical guides 50 fixed to the side plate of the section. The other extremity of the bar or beam 41 has similarly pivotally attached to it a cross-head and pair of links, the former working in vertical guides 51 in like manner. The other and lower extremities of the links 46, 47 are pivotally attached to a lever 52 which is fulcrumed on a spindle 53 fixed to the side plate, and has attached to it a pinion 54. The weighted lever 43 is fulcrumed on a spindle 55, and has attached to it a pinion 56, whichmeshes with the pinion 54. By means of this arrangement both ends of the beam 41 are drawn down into contact with the top of the truck when the truck tippler is rotated in the direction to incline and empty the truck.

As shown in-Fig. 5 the weighted levers 42, 43 are slightly inclined toward the right so that when the truck is man upright position they operate through their respective levers and links to maintain the bar or beam 41 in its uppermost position clear of the top of the truck. The guides 50, 51 through the cross-heads 49 serve as stops to limit the up ward movement of the beams. The weights on the levers 42, 43 are so designed that their aggregate Weight is sufiicientto securely clamp any truck in the tippler.

'In Figs. 8 to 10 I illustrate a modified arrangement of the means for automatically operating the clamping beams or bars 41. In this construction a pair of links, crosshead, pin and uides are provided as described in the last construction for each end of the clamping bar or beam 41. The links on the one side are pivotally connected to a lever 57 which is fulcrumed on a spindle 58 and is attached to apinion 59. 60 is an actuating lever fulcrumed on a spindle 61 and connected with a pinion 62 which meshes with the pinion 59. The pinion 62 may be of the same size as, or if preferred larger than, the pinion 59. The lever 60 is fashioned with a head or protuberance 63 in the form of a sector which is provided with a groove 63. 64 is a rope which at one end passes around the groove in the sector or curved surface of the head or protuberance fashioning the outer end of the lever 60 as shown and attachin the rope thereto in the manner explained t e outer end of the lever 60 is thrown slightly inward or toward the center of the tippler which through the pinions 62, 59, lever 57 and links operates to maintain the clamping bars or beams in their uppermost position and clear of the top or upper edges of the sides of the truck when the latter is in an upright position.

68 is a further lever fulcrumed on a spindle 69 and attached at its other endto the links 46, 47 which are connected to the opposite end of the bar or beam 41. The motion of the'lever -57 is transmitted to the other lever 68 by means of two bell, crank levers 70, 71 fulcrumed on spindles 72, 73

fixed in the one case to the side plate of the section and in the other to a bracket 74 secured to said side plate; 75 being a connecting rod between the lever 57 and one arm of the bell crank lever 71 and 76 a similar connecting rod between one arm of the other bell crank lever 70 and the lever 68. 77 is a rod connecting the other arms of the bell crank levers. The manner in which this arrangement operates will be readily understood on reference to Fig. 8 in which the parts are shown in full lines when the tippler is in its lowermost position and the truck upright, and in dotted lines when. the tippler is in its uppermost position and has been partially rotated to incline the truck.

During the raising or lowering of the tippler the weight maintains the lever substantially vertical or with a slight inclination toward the truck which as previously explained operates to keep the beam or bar in its uppermost position clear of the top of the truck. When the tippler is in its uppermost position and its rotation has commenced, in order to tip the truck the Weight acting through the lever 60 will move the barsor beams into contactwith the upper edges of the sides of the truck. \Vhen the bars or beams are in this position the weights will continue to be raised so long as the rotation of the tippler continues in the same direction. WVhen' the direction of the rotation of the tippler is reversed to place the truck in mately operate to release the bars or beams from the upper edges of the sides of the truck and place them in their uppermost position as shown in Fig. 8. As thetippler descends the weight will then be raised from the position in which it is shown in dotted lines to that in which it is shown in full an upright position the weight will ulti- 1 lines in Fig. 8. It will be evident that the weights 67 will serve to partially counterbalance the tare weight of the tippler.

For the purpose of bringing'the loaded trucks to rest in a symmetrical position in the tippler and to obviate the placing of unequal stresses upon its structure and to save time in shunting the trucks on to the carriage of the tippler, the rails 33, 34 which are carried by said carriage or traverser are, as shown in the drawings, preferably provided at conveniently placed distance apart, corresponding to the wheel bases of the truck to be tipped, with slight concavities or shallow depressions. The rails 33, 34 may,-for example, be provided with concavities or depressions 78 for bogie trucks (the truck 35 shown in position in the tippler in Fig. 4 is a bogie truck) and with other concavities or depressions 79 for ordinary trucks. The radius of the concavities 78, 79 will preferably be the average radius of the wheels of the trucks. The concavities being slight, the empty trucks can be easily pushed or hauled overthem out of the tippler.

In connection with Figs. 1, 2 and 3 I illustrate the means for manipulating the ropes, chains or their equivalent for lifting the tippler together with the truck to the requisite height to discharge the contents of the latter, located upon the platform provided by the top of the arches 14 of the superstructure. As shown these meanscomprise two winding drums 80, 81 of the same diameter and driven at the same rate of speed. The driving means are shown consisting of an electric or other suitable motor 82, a worm 83 on the mote-r shaft 84, a worm wheel 85 fixed upon a shaft 86, bevel wheels 87, 88 on opposite ends of the shaft 86, further bevel wheels 89, 90 which mesh with the bevel wheels 87, 88 respectively, pinions 91, 92 which are driven through the bevel gears by shafts 93, 94 and large spur wheels 95, 96 connected with the drums 80, 81 respectively. 97, 98 represent the brake surfaces of the drums. 99, 100 are two lifting ropes for the tippler, one operated by each of the drums 80, 81. Both ends of each rope are attached to opposite ends of their respective drums, being coiled upon them in the same direction so that both ends of the rope are wound upon the drums when they are moved in one direction and unwound when the drums are moved in the opposite direction.

The bights or loops of the two ropes 99, 100 pass around suitably positioned guide pulleys fixed to the front of the tippler and serve as slings for manipulating the tippler or for raising, rotating and lowering the same. 101, 102 representthe pulleys for the one rope 99 (hereinafter styled the front rope) and 103, 104 are the pulleys for the other rope 100 (hereinafter styled the back rope). The rope 100 as shown-see more particularly Figs. 4 and 5-passes underneath the tippler and over the guide pulleys 103, 104. The sections to which the guide pulleys 101, 102, 103, 104 for the ropes 99, 100 are fixed are provided with, circumferential bands or rings providing guiding grooves 107, 108 for the ropes. provided in the bands or rings in which the pulleys 101, 102, 103, 104 are positioned. 109, 110, 111, 112 are guide pulleys for the front rope conveniently arranged in relation to the drum 80, and 113, 114, 115, 116 are similar guide pulleys for the back ro e 100.

. t will be understood that by winding the two ropes 99, 100 upon their respective drums at the same speed the tippler can be lifted to the desired height. When the tippler has reached the requisite height the front rope 99 is paid out or uncoiled off its drum 80 and the winding of the back rope 100 upon its drum 81 continued. This has the effect of rotating the tippler and bringing itin the position in which it is shown in dotted lines in Fig. 1, thereby inclining the truck and discharging its contents.

To enable the direction of motion of the front drum 80 to be reversed in order to rotate the tippler as above described a bevel wheel 117 and a clutch 118 are provided. By means of the clutch 118 either bevel wheel 87 or bevel wheel 117 can be employed for transmitting the motion from shaft 86 to bevel wheel 89. Y

The means for actuating the clutch 118 may be operated either by hand or automatically by the movement of the tippler. I show a hand-actuated means for the purpose, arranged on a platform or cabin 119, said means comprise a hand-wheel 120 which operates a vertical spindle 121 through bevel wheels 122,123, the motion of spindle 121 being transmitted to a further spindle 124 through bevel wheels 125, 126. The latter spindle 124 operates the clutch lever 127 through the medium of a screw 128 and a nut 129 attached to the clutch. lever 127. 130 is an indicator, arranged so as to be visible to the operator, for indicating the position of the clutch.

If desired means may be provided for preventing the truck being inclined beyond an angle which will be suflicient to insure the complete discharge of its contents. 1

As will be understood the reversal of the motor and the due operation of the clutch mechanism--when the tippler has been rotated to place the truck in an upright position-will result in the lowering of the tippler and the empty truck, the automatic release of the clamping beams 41-which will Gaps are have come into operation when the tippler sition in which the latter can be run out of the tippler along the rails 1O of the main track. L

131 is the controller for the electric motor which is arranged on the platform or cabin 119 in close proximityto the hand-wheel 120 of the clutch mechanism.

Means are provided for counterbalancing the weight of the tippler plus a weight slightly less than the tare weight of the smallest truck which it is intended to accommodate or receive in the tippler. The means shown for accomplishing this consist of three weights 132, 133, 134 which weights are uided in grooves 135 in the pillars 13. Tfies'e weights operate through three ropes 136, 137, 138. 'For each of the ropes guide pulleys 139, 140, 141, 142, 143 are provided. The ropes are'attached to the center and two outer sections of the tippler which sections are also provided with circumferentially grooved bands for the three counterbalancing ropes 136, 137, 138'. As shown in Fig. 4'one end of each counterbalancing rope is attached at 147 in the gap in its respective band. The rope as shown in Figs. 1 and 3 then passes over the guide pulley 139 then over the guide pulley 140 under the guide pulley 141 (attached to its weight 132, 133 or 134) then over the guide pulley 142 and over guide pulley 143, then underneath the tippler to which the other end of the rope is attached at 148see Fig. 4. The several bands or rings in their lower portions or from the point 149 to the oint 150see Fig. 5-are made'solid or 0 rectangular cross section and have the rope groove formed therein. The solid portions of the rings rest upon the bolster 11 and serve to protect the ropes when the tippler is in that position.

The counterbalancing means are shown utilized for operating means which bring into position beneath the inclined truck a hinged chute 151 which receives the contentsof the truck when it is tipped and delivers the same into a fixed chute 152 which in turn will deliver it outside the superstructure. The said operating means as shown consists principally of three differential drums 153, 154, 155 one for each of the counterbalancing weights 132, 133, 134; two ropes 156, 157, three other ropes 158, 159, 160, and three weights 161,163, 163. The ends of one of the ropes (156) are fixed to I the larger sections of .two of the differential drums 153, 155 and one end of the other rope is also fixed to the larger section of the other differential drum 154. The rope 156 one end of which is attached-to the larger section of the differential drum 153 passes over a guide ulley 164 arranged in front of the drum and then in a downward direction and underneath a number of guide pulleys 165 which are rotatably attached to the one end section of the tippler, then to and around which is hinged to the edge of the chute near the other side, then under a number of guide pulleys 168 which are rotatably attached 'to the other end section of the tippler and then around av guide pulley 169 which is arranged in front of the other differential drum 155' to which this, the other end, of the ro is attached. As shown in Fig. 7 the hinged guide pulleys 166, 167 are preferably provided with guides for the rope. The other rope 157 is attached at one end tothe larger section of the third differential drum 154 which is intermediate the other two differential drums 153, 155. This rope 157 passes off the drum and around a guide pulley 170 arranged in front thereof, then down to and under the several guide pulleys 171 which are rotatably attached'to the middle section of the tippler, and then to the chute 151 to which it is attached at a smaller sections of the three differential drums 153, 154, 155. The said ropes then pass through holes in the ends of arms 172 connected to the counterbalancing weights 132, 133, 134. To the lower ends of the ropes 158, 159, 160 there are attached the three weights 161, 162, 163. The length of said three ropes is such that the arms 172 do not depress the weights 161, 162, 163 until the tippler has been lifted clear of the hinges of the chute 151. The depression of the three weights 161,162, 163 by the arms 172 unwinds the three ropes 158, 159, 160 ofi the smaller sections of the three differential drums 153,

reaching its maximum height.

The rope 157 and the intermediate differential drum 154 and the other parts cooperating therewith might be dispensed with and the one rope 156 and the two differential drums 153, 155 and their coiiperating parts be alone used for actuating the chute.

Brake bands, actuated electrically by the controller 131 or otherwise, can be fixed on, or combined with, the diiferential drums 153, 154,155, in order to keep the chute 151 positively in the inclined position during the tipping operation.

As shown in Figs, 1 and 2 counterbalancing Weights 173 may be fixed to arms attached to the hinged end of the chute 151 to assist in the raising of the chute into its operative position beneath the truck.

The fixed chute 152 as shown, in Fig. 1 may be curved at the bottom in its upper portion as indicated at 152 to prevent any accumulation of the material at that point, and also to insure a gradual fall of the material as it enters the fixed chute 152 from the movable chute 151.

In Fig. 11 I illustrate an alternative arrangement of the lifting and revolving ropes for the tippler, in which the front rope 174 passes around guide pulleys 175, 176 fixed to the front of the tippler as in the last described arrangement. The back rope 177 passes off one end of the drum underneath the tippler, then over guide pulleys 178, 179 at the front of the tippler, then under thetippler, then over any suitable arrangement of guide pulleys represented by the circles 180, 181 then underneath the other end of the tippler, then over' guide pulleys 182, 183 at the front of the tippler, then under the tippler and back to the other end of the drum. The three ropes 184, 185, 186 for the three counterbalancing weights are arranged and connected to the tippler in the same manner as in the first described construction.

With the arrangement above described (Fig. 11) the drum 81 to which the two ends of the back rope 17 7 are attached and upon which said rope is wound must be twicethe diameter or be driven at twice the speed of the other drum 80 to which the ends of the front rope 174 are attached and upon which said rope is wound. This arises owing to the fact that the drum 81 during any given period has to take up or pay out twice the length of rope that the other drum 80 has.

In Fig. 12 I show a further alternative arrangement of the lifting and revolving ropes for the tippler. In this case also the front rope'187 passes around guide pulleys 188, 189 fixed to the front of the tippler asin the two previously described arrangements. The back rope 190 passes off one end of the drum underneath the tippler then over a guide pulley 191 fixed to one section; then around two guide pulleys 192, 193 fixed to the adjoining end section, then around two guide pulleys 194, 195 fixed to the other and opposite end section, then around another pulley 196 fixed to the section adjoining said latter section, then under the tippler and back to the other end of the drum. The three counterbalancing ropes 197, 198, 199 are arranged in the same manner as in the two previously described constructions.

It is evident that the means for clamping the truck in the tippler may in the one tipping apparatus comprise a combination of the two means illustrated in Figs. 1 and 8, that is to say, that certain of the clamping bars or beams 41 can be actuated by weighted -levers 42, 43-see Fig. '1and other similar clamping bars by the weights 67-see Fig.

8-in which event the weighted levers 42, 43'and weights67 would cooperate to clamp the truck 35 in position in the tippler.

Suitable tripping devices or limiting switches, such as are commonly provided in ,many hoists, may be utilized for preventing overwindlng.
